DETERMINATION OF CHEMICAL COMPOSITION AND CRYSTAL PHASE OF FUME BY X-RAY FLUORESCENCE AND X-RAY DIFFRACTION ANALYSIS

INDUSTRIAL HEALTH, 1970
A combined use of X-ray fluorescent analysis and X-ray powder diffraction analysis is proposed for collecting precise and systematical information about the fundamental characteristics of fume from very small amount. This method, completely non-destruc-tive in most cases, can analyze directly the samples collected on filter paper and is able to ...

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...
